1. Carbon footprint is in the news a lot these days.
2. It’s better to have a bigger footprint.
3. Non–renewable energy sources like coal, natural gas, and oil.

1. Listen and read.
Mai: Nam, I read yesterday that we all have a carbon footprint.
Nam: Well, we all have footprints–we make them with our feet!
Mai: Ha ha, I know that. But this kind of footprint is about the negative effect we have on the environment.
Nam: Right, it’s in the news a lot these days.
Mai: So our footprint is bigger when we use energy that produces carbon dioxide. That’s bad for the environment.
Nam: So it’s better to have a smaller footprint, right?
II. Practice :
Mai: Right, Nam. Non-renewable energy sources like coal, natural gas, and oil produce a lot of carbon dioxide .Those sources are going to run out soon, too.
Nam: So, they’re different to wind, hydro, and solar?
Mai: Yes, they’re all sources of energy too, but they’re renewable. That means they can use them all up – They will last forever.
Nam: Do you have a big carbon footprint, Mai ?
Mai: Mine’s small. I recycle the products I use and I go everywhere by bike. We have solar panels on our roof at home to catch the sun’s energy, too.
Nam: Oh no! I think my footprint is big, and not just because of these big shoes!

1. What is a carbon footprint?
It’s about the negative effect we have on the environment.
Lucky number
2. What does “non renewable energy” mean?
Non –renewable energy means that it will run out if we use it.
Lucky number
3. Why is sunlight a renewable source?
Sunlight is a renewable source because we can’t use it all up, it will last forever.
4. Why does Mai think she has a small carbon footprint?
Because she recycles the products she uses and she goes everywhere by bike.
5. What things do you think might create a big carbon footprint?
The products we use that are bad for the environment or the energy we use that produces carbon dioxide might create a big carbon footprint.

* Dấu chân carbon” là gì? (What is carbon footprint ? )
Tác động của bạn đến môi trường mạnh đến cỡ nào, những hành động thường nhật của bạn thải thêm vào khí quyển bao nhiêu khí carbonic (CO2); tất cả những số liệu đó sẽ được tính toán đo lường và hiển thị bằng một con số mà chúng ta gọi là carbon footprint – dấu chân carbon. Con số của bạn càng lớn thì tác động xấu của bạn đến môi trường càng mạnh, tựa như một dấu chân khổng lồ in lên bề mặt trái đất vậy.
Theo như lý tưởng mà nói, thì khi một người nhìn thấy con số dấu chân carbon của mình và nhận ra cách sống của họ ảnh hưởng đến trái đất nhiều đến mức nào, họ sẽ bắt đầu thực hiện những thay đổi để giảm số dấu chân carbon của mình.
Homework
1. Learn by heart vocabulary introduced in the lesson.
2. Re-read the dialog.
3. Write a paragraph: how to reduce carbon footprint.
4. Prepare new lesson : Unit 10. A closer look1.
